The Keyboard (Windows)
Typing with the keyboard is comfortable, relatively quiet and smooth. There hasn't been any missed keystrokes when I'm playing StarCraft 2 or Battlefield 3 (even at night). The design is stylish and incredibly slim, only 1/3 inch thick (about 9mm).
Installation of the SetPoint and Solar App are a breeze as it is done automatically when the keyboard is recognised by Windows. The Logitech Unifying Receiver can also pair with a compatible mouse using just one USB port, which is great for those running low on number of available ports.
There are hot keys which are available when pressed with FN key. These keys invokeyour internet browser home page, email, search, calculator, media player, song navigation (previous, play, pause, next), sound (mute, level up, level down), shutdown computer and mouse right-click. The only problem is FN key is on the right side of the keyboard which is far from F1 - F4 which makes single hand controls tough. However you probably be not bothered by it so long you use both hands to type most of the time.
There are no lights to signal if Caps Lock, Num Lock or Scroll Lock is on. However a on-screen display is there whenever you press one of these.
The keyboard has a rechargable button battery cell (ML2032) which eliminates changing of batteries. You can check the status of the battery via a Solar App (left) which will launch by pressing the "Light-Check" hot key on the keyboard. The LUX level will also be shown so that you will know if the light is enough for charging; the manual states to keep the LUX level at 100 or higher to make sure that there will have plenty of energy. When fully charged, it can last at least 3 months without light.
I have been using the Windows version for about 5 months now, and the battery has never went below 98%.You can see from the image (left) that the LUX level is low which is the usual case for the night, and during the day the LUX is about xx from the indirect light source. My keyboard is about 1.5m away from the windows, thus it does charge the battery based on what it claims. It's a wonder that the keyboard can actually power itself with the button battery cell when compared to others that needs AA batteries.
The replacement battery is not available in stores, but can be purchased from Logitech as per this link, together with other replacement parts.
What could have make it better?
- Illuminated keys with LED lights powered by a second rechargable battery
- Switch to toggle from Windows to Mac or vice versa together with replaceable keys
- Switch to toggle F1-F12 to keyboard hot keys instead of always requiring the user to press FN (Windows keyboard)
